[Since Nagisa had trekked all the way out into the Spring segment to dye some cloth, he thought he'd take a look at the Cherry Blossom Park, since hey, it's in the area, isn't it?

However, having mostly ignored the quest board, he did not expect the giant butterflies hanging around the park, though. Or for one of them to be following him around and gently nudging his shoulder as if to get his attention.]

...Are you asking for food?

...I'm sorry. I didn't bring any food that's suitable for a butterfly.

[He does feel bad for the creature, though, so he's looking around for a suitably giant flower, or anyone who seems more familiar with the giant butterflies in general.]
